相位幅度调制(Phase Amplitude Modulation),采用多相PSK可以有效提高数据传输速率,但受实际电话传输网的限制,相移数已达到上限,再要提高数据传输速率,只能另寻它法。PSK和ASK技术的结合,可以解决这个问题。 例如,采用12种相位,其中4种相位每个信号取2种幅度,这样就得到16种不同的相位幅度离散状态,可以使一个码元表示4...

1 ASK调制 振幅键控是利用载波的幅度变化来传递数字信息, 而其频率和初相位保持不变。二进制幅度键控 (2ASK) 方式是数字调制方式中出现最早也是最简单的一种方法。这种方法最初用于电报系统, 二进制振幅键控常常作为研究其它数字调制方式的基础。2ASK调制信号只有0或1两个电平相乘的, 结果相当于将载频或者...
